Affairs of the wounded heart: penetrating cardiac wounds
Insights
This study on penetrating cardiac wounds found that early surgical intervention, like thoracotomy for shock or pericardial window for tamponade, improved survival. Most wounds were repaired with sutures, with cardiopulmonary bypass rarely needed.
Area of Science:
- Cardiovascular Surgery
- Trauma Surgery
- Emergency Medicine
Background:
- Penetrating cardiac injuries pose significant mortality risks.
- Effective management strategies are crucial for improving patient outcomes.
Purpose of the Study:
- To analyze the outcomes of patients with penetrating cardiac wounds.
- To evaluate the effectiveness of different surgical approaches.
Main Methods:
- Retrospective review of 100 consecutive patients with penetrating cardiac wounds.
- Analysis of injury types, surgical interventions, and patient outcomes.
- Comparison of management strategies for hemorrhagic shock versus cardiac tamponade.
Main Results:
- Overall mortality rate was 11%, declining to 8% in the last 4 years.
- Right ventricle (46) and left ventricle (30) were most frequently injured.
- Subxiphoid pericardial window was effective for cardiac tamponade management.
Conclusions:
- Prompt surgical intervention is key for managing penetrating cardiac wounds.
- Specific approaches for shock and tamponade syndromes improve survival rates.
- Direct suture repair is often sufficient, with complex interventions used sparingly.
Abstract:
During the 10-year period ending 1 March 1978, 100 consecutive patients with penetrating cardiac wounds entered the Bexar County Hospital with some sign of life. The early and late mortality rate, 11%, declined to 8% during the last 4 years. Noncardiac injuries were responsible for six of the eleven deaths. Complications occurred in 17. The most frequently injured chambers were the right ventricle (46) and left ventricle (30). Sixty-nine patients had stab wounds and 26 had gunshot wounds. Pericardiocentesis was falsely positive or negative in 12 of 47 patients. Two distinct syndromes were apparent, hemorrhagic shock and cardiac tamponade. Patients with shock had immediate thoracotomy. Patients with suspected tamponade had a subxiphoid pericardial window, under local or light general anesthesia, for diagnosis and decompression before endotracheal intubation and sternotomy. Most wounds were repaired by direct suture. Cardiopulmonary bypass and thoracotomy before arrival in the operating room were rarely indicated.
